I can't say it is all well as we are having issues - tasks sitting as queued and timing out, many errors in Altiris logs, SMA logs...
Anyway I believe the packages should have been removed by the upgrade.
The path was the old 7.1 - \\nsServer\Deployment\etc...
Also drivers seemed WinPE2
Log entries look like the one below and it was flooding the logs:

</event>
